SAMPLE A natural mixture of Ca isotopes was used for C024900100015
irradiation. The target was pressed in the shape of a C024900100016
rectangular wafer (15x4x1.5 mm) from calcium carbonate.C024900100017
DETECTOR (NAICR) A scintillation gamma-spectrometer having a C024900100018
NaI(TI) 40 x 40 mm crystal and a 128-channel AMA-3c C024900100019
analyser. C024900100020
METHOD (ACTIV,CHSEP) The target was irradiated in the C024900100021
internal beam of the synchrocyclotron of the Joint C024900100022
Institute for Nuclear Research for 15 to 20 min. The C024900100023
proton beam was parallel to the 1.5 mm side of the C024900100024
target. The incident proton energy was varied by C024900100025
positioning the target at different radii in the C024900100026
accelerator chamber. The irradiated target was C024900100027
dissolved in a small amount of diluted HC1 with ~ l0 C024900100028
mg of Sc carrier. After CO2 has been removed by C024900100029
boiling the solution, scandium hydroxide was C024900100030
precipitated by addition of NH4OH. Then the calcium C024900100031
and scandium fraction were purified radiochemically. C024900100032
The proton beam intensity was determined by the yield C024900100033
of the A127(p,3pn)Na24 reaction. The target was C024900100034
wrapped in three layers of 20 micron aluminum foil. C024900100035
To measure the Na24 activity, middle layers on both C024900100036
sides of the target were used. The layers had been C024900100037
cut strictly to the size of the target. The C024900100038
difference in the activities of these foils did not C024900100039
exceed 10% and amounted on the average to some 5%. C024900100040
The ratio of absolute activities of the reaction C024900100041
products and Na24 was derived by comparing the C024900100042
intensities of characteristic gamma-lines, taking C024900100043
into account the decay schemes and the efficiency of C024900100044
counting. C024900100045

ERR-ANALYS (DATA-ERR) The cross sections indicated are averages C024900100049
of two or three measurements with quadratic mean C024900100050
errors. The general accuracy for the cross sections C024900100051
is estimated to be about 15%. Besides, the cross C024900100052
sections contain errors due to uncertainties in the C024900100053
decay schemes and in the cross section for the C024900100054
monitoring reaction. C024900100055
